      Next Generation CT Scanners for Lung Cancer Screening – Way Forward Sebastian Schmidt, Siemens Healthcare GmbH, Siemensstr. 3, 91301 Forchheim, Germany After the publication of the NLST (National Lung Cancer Screening Trial) in 2011, lung cancer screening with low dose computed tomography gained more and more attention and was formally established in the USA in 2016 and other countries afterwards. The increasing use of CT for screening created new requirements for computed tomography scanners: - Further reduction of radiation dose: As the target population is healthy and gets repeated scans, cumulative dose is an important topic. This is addressed by technologies like improved spectral shaping and iterative reconstruction. - Quality control and standardization: A homogeneous high quality is extremely important in screening. This will be enabled by cloud-based technologies for distribution of protocols, central registration of scan parameters and radiation exposure and collection and distribution of images between many scanners and many radiologists. - Affordability: Lung cancer screening should be economically feasible in different healthcare systems. Therefore new technologies are required to improve throughput and decrease effort as well as to provide ultra-low-dose technologies on cost efficient CT systems. - Ability to combine lung cancer screening with other biomarkers for common diseases like COPD or arteriosclerosis. The academic community and the CT vendors spent significant effort into development and clinical validation of CT systems meeting these requirements. Many technologies are already available today, others are under development. Some research and development activities: - Ultra-low-dose CT with less than one tenth of the natural background radiation. - Cloud-based systems for distributed standardization, reporting and quality control of large fleets of scanners. - Highly cost-efficient systems with these technologies. - Semi-automated scanning and reporting aids to reduce the workload of the technologist and the radiologist. - Development of protocols to assess several parameters in an ultra-low-dose scan. Some of these technologies are already commercially available on the latest systems, others are under research. Help from the clinical community is required in validation of these technologies and the definition and standardization of the best clinical and scanning protocols.
